Timeline controls
|
|
--------------------------
|
|
|
|
The timeline controls sit at the top of the timeline panel and allow you to control the playback and what [timeline](../../concepts/logging-and-ingestion/timelines.md) is active.

It lets you select which timeline is currently active and control the replay of the timeline.
|
|
These controls let you stop play/pause/step/loop time just like a video player.
|
|
When looping you can choose to loop through the whole recording, or just a sub-section of timeline that you select.
|
|
The rate of playback can also be sped up or slowed down by adjusting the rate multiplier.

Streams
|
|
-------
|
|
|
|
The Streams panel can be hidden with the layout config buttons at the top right corner of the viewer.

On the right side you see circles for each logged [event](../../concepts/logging-and-ingestion/timelines.md) on the currently selected timeline over time.
|
|
You can use the mouse to scrub the vertical time selector line to jump to arbitrary moments in time.
|
|
The stream view allows panning with right click and zooming with `ctrl/cmd + scroll`.
|
|
|
|
|
|
The tree on the left shows you all entities that were logged for this timeline.
|
|
When you expand an entity you will see both the components that are associated with it, as well as any child entities.
|
|
Selecting entities or events in the streams view shows additional information in the selection panel about them respectively.
|
|
|
|
### Discontinuity skipping
|
|
Rerun automatically detects discontinuities in the selected timeline and will skip over them while playing.
|
|
This is particularly useful whenever you have large gaps in the timestamps of your data recordings.
|
|
Detected discontinuities are visualized with a zigzag cut in the timeline.
|
|
|
|
[TODO(#1150)](https://github.com/rerun-io/rerun/issues/1150): Allow adjusting or disabling the time-discontinuity collapsing.
